Why the study?
Does the incorporation of LV GLS into a staging classification improve risk stratification in patients with severe aortic stenosis?
Does the incorporation of LV GLS into a staging classification improve risk stratification in patients with severe aortic stenosis?
Adding left ventricular global longitudinal strain to staging classifications for severe aortic stenosis improves risk stratification by identifying advanced cardiac damage.
LV GLS may refine severe AS staging; leaves open prospective validation before practice change.
In this large single-centre cohort of severe AS patients, incorporation of LV GLS by quintiles in a novel proposed staging classification resulted in refinement of risk stratification by identifying patients with more advanced cardiac damage. LV GLS was shown to provide incremental prognostic value over the originally proposed staging classification.
